Structural Features:

1.Use a cylinder as the actuator to drive the gate directly the gate directly to move up and down, with fast opening/closing.

2.The double gates adopt floating connection to produce reliable one-way seal under the medium pressure action. Also the floating connection can drive the gate to rotate up in opening/closing due to misalignment of axial lines so that the friction grains between the valves¡¯s gate and seat are distributed evenly to produce no linear abrasion, thus improving its service life greatly.

3.Sealing surfaces of the valve¡¯s body and gate are lined with anti-wear ceramics,with excellent resistance to abrasion.

Working principle

When the cylinder drives the gate to move downwards through the valve¡¯s stem, sealing surfaces of the valve¡¯s gate and body will be engaged to cut off the channel, namely, closing; the other way around is opening.
